dix: Drop the third argument from WindowExposuresProcPtr

Browse Source 
A careful read shows that it was always NULL.  It hasn't always been; as
the DDX spec indicates, it was the "occluded region that has backing
store", but since that backing store code is long gone, we can nuke it.

mi{,Overlay}WindowExposures get slightly simpler here, and will get even
simpler in just a moment.
